MOSQUITO-NET FRAME.

SPECIFICATION forming part of Letters Patent No. 247,244, dated September 20, 1881.

Application filed March 12, 1881. (No model.)

To all whom it may concern Be it known that I, AMANDA M. DOUGLAS, of Newark, in the county of Essex, State of New Jersey, have invented a certain new and useful Improvement in Mosquito-Net Frames, of which the following is a description sufliciently full, clear, and exact to enable any person skilled in the art or science to which my invention appertains to make and use the same, reference being made to the accompanying drawings, forming a part of this specification, in which- Figure l is a vertical longitudinal section, showing the frame in use with a full net. Fig.

2is a like view, showing it in use with'a half net. Fig. 3 is a sectional view of one of the joints. Fig. 4 is a side elevation, showing the frame folded; and Fig. 5, a sectional end elevation.

Like letters of reference indicate corresponding parts in the different figures of the drawmgs.

My invention relates more especially to that class of mosquito-net frames which are portable; and it consists in a novel construction and arrangement of parts, as hereinafter fully set forth and claimed, by which a simpler, cheaper, and more effective device of this character is produced than is now in common use.

In the drawings, A represents the headboard, B the foot-board, and C the side rail, of an ordinary bedstead, the rail being provided with a ledge or shelf, (1, on which are disposed a series of horizontally-arranged cross-slats, a, in the usual manner.

The main frame consists of the two horizontal rails H, the two vertical bars E, and the two top rails or cross-bars f. The rails H are respectively jointed to the bars E by the bolts w, and to the upper ends of these bars are hinged the cross-bars f, as seen at n, theinner ends of the cross-bars being also hinged together, as shown at 1".

An auxiliary frame composed of two vertical bars,F, corresponding with the bars E, provided with hinged cross-bars (not shown) corresponding with the cross-barsf, is employed as a foot-piece to the main.frame, being arranged, when in use, as shown in Figs. 1 and 2.

For the purpose of connecting the auxiliary frame with the main frame, and supporting it in proper position for use, the lower or free ends of the rail H are provided, respectively, with lateral mortises v,into which corresponding clips or tenons on, attached to the lower ends of the bars F, are fitted, thus forming the separable joint 2.

In the use of my improvement the rails H of the main frame are arranged horizontally on either side of the bed, in juxtaposition to the side rails, O, or in such a manner as to rest on the slats a, between the edges of the mattress and sides of the bedstead. The bars E, carryin g the cross-bars f, are then elevated to a vertical position, as shown in Fig. 5, after which. the auxiliary frame is set up by connecting the bars F to the rails H by means of the clipor tenon m and mortise 'v, the frame being then ready to receive the net or canopy I).

When not in use the main frame may be readily and compactly folded by bringing the rails H into parallelism with the bars E and closing the cross-bars f upon each other, as shown in Fig. 4, the auxiliary frame being folded in a similar manner. The upper ends of the bars E, on their inner sides, are chainfered or beveled to an angle of forty-five degrees, and the outer ends of the bars f, on their lower sides, are correspondingly beveled, as seen in Fig. 4, so that when the frame is arranged for use, as shown in Fig. 5, a self-supporting or bracejoint is formed at n. The inner ends of the cross-bars fare also connected by means of a rule-joint, 1", having its shoulder uppermost when the frame is in use, to preserve the bars in a horizontal position or prevent them from sagging.

When the frame is not sufficiently well supported or kept in position by the mattress and side rail, 0, an ordinary screw-clamp or any other convenient means may be employed to firmly secure the rail H to the slats a. The frame may also be adapted to bedsteads of different widths by making the cross-bars foxtensible.

It will be obvious that the bars E may be connected to the rails H by separable joints; also, that the auxiliaryframe may be dispensed entirely departing from the spirit of my invenand arranged to operate substantially as and 10 tion. for the purpose specified. l

with,or more than one used,ifclesired,without [hinged or jointed together, and constructed l Havlng thus explalned my improvement, AMANDA M DOUGLAS 5 what I claim is-- The mosquito-net frame described, the same Witnesses consisting of the horizontal rails H, cross-bars U. A. SHAW, f, vertical bars E, and detachable bars F, I ANNIE D. BELL.
